Sebastien De La Cruz brushes off the racism

Sebastien De La Cruz, 11, performed the National Anthem at Game 3 of the NBA Finals in San Antonio on Tuesday night, filling in for country crooner Darius Rucker, who had to cancel at the last minute.

By all accounts, Sebastien, a former "America's Got Talent" performer, brought the house down with his rendition of "The Star-Spangled Banner." Some viewers, however, fired off racist comments on social networks like Twitter following the performance.
